Alarm Function

Alarm output

The Alarm action point is set as a ±deviation from SV (except Process alarm). When the PV is out of the range, the alarm output turns ON or OFF (in the case of High/Low Limit Range alarm).
If the Alarm Function is specified, one type can be selected with the DIP switch: No Alarm Action, High Limit alarm, High Limit with Standby alarm, Low Limit alarm, Low Limit with Standby alarm, High/Low Limits alarm, High/Low Limits with Standby alarm, High/Low Limit Range alarm, Process High alarm and Process Low alarm.
